The black vulture is aggressive when feeding and may chase the slightly larger turkey vulture from carcasses. [49] The black vulture also occasionally feeds on livestock or deer. It is the only species of New World vulture which preys on cattle. It occasionally harasses cows giving birth, but primarily preys on newborn calves, lambs, and piglets.
A vulture is a bird of prey that scavenges on carrion. There are 23 extant species of vulture (including condors ). [ 2 ] Old World vultures include 16 living species native to Europe , Africa , and Asia ; New World vultures are restricted to North and South America and consist of seven identified species, all belonging to the Cathartidae family .
A portrait of the cinereous vulture, also known as the Eurasian black vulture. The cinereous vulture measures 98–120 cm (39–47 in) in total length with a 2.5–3.1 m (8 ft 2 in – 10 ft 2 in) wingspan. Males can weigh from 6.3 to 11.5 kg (14 to 25 lb), whereas females can weigh from 7.5 to 14 kg (17 to 31 lb).

The pelvis is, in general, different between the human female and male skeleton. [12] [13] Although variations exist and there may be a degree of overlap between typically male or female traits, [12] [13] the pelvis is the most dimorphic bone of the human skeleton and is therefore likely to be accurate when using it to ascertain a person's sex ...
However, such sex differences are primarily limited to the anthropoid primates; most of the strepsirrhine primates (lemurs and lorises) and tarsiers are monomorphic. [2] Sexual dimorphism can manifest itself in many different forms. In male and female primates there are obvious physical difference such as body size or canine size.
Male platypuses have sharp spurs on their back legs shaped like a canine tooth. These hollow spurs measure 0.59 to 0.71 inches long and connect to crural glands in the animal’s upper thighs.
The black vulture (Coragyps atratus) [6] has a large, jet-black body, short black tail, white primary patches, and whitish legs. They live within open habitats but along the edges of forests . The length of their bodies is 59–74 cm, with a wingspan of 141–160 cm and weight of between 1.7 and 2.3 kg.
